我应该提到的是，如果你使用的是Mac，从应用商店下载并运行一个应用程序(如“iBoostUp”等)，它将清理不使用的系统文件，可以大大加快你的计算机，包括AS。 我还发现，为我的Mac添加更多内存也能提高AS速度。

这里让我感到痛苦的不是编译，而是输入。我可以禁用所有智能功能，回到notepad++，就像TomTsagk在评论中建议的那样。今天我需要更多的核心和内存。

作为魔鬼的拥护者，我认为打字不应该需要16Gb的八进制PC。喜欢Sajan Rana的建议，但这里的事情太缓慢了，感觉像是安慰剂。

为了公平起见，我使用的是1.4RC1，它离稳定分支还差得远。关闭互联网有一点帮助。同时使用XML布局的设计(预览)和文本视图的新特性非常有用。

不，这太荒谬了。永远不要离开稳定的航道。

提高android studio运行时性能的最佳方法是使用SSD Drive。这将极大地提高性能。我做了以上所有的事情，觉得我应该去买一台新的笔记本电脑，但突然我知道了SSD驱动器，我尝试了一下。Its Much Much better.....

我注意到AS从HDD传输了太多的数据。这是非常烦人的，尤其是在开始写一行新代码的时候。所以，我认为更好的办法是用SSD重新安装硬盘。我的i5有6gb内存，即使在构建时，CPU的负载也很少超过50%。所以，最薄弱的地方是HDD。

杀毒软件导致了慢速

In one particular system I looked at, this issue was caused by an over-zealous anti-virus that was interfering with Gradle, the build manager for Android Studio. It seems every time Gradle was "touching" a .jar file, the virus checker was unzipping the .jar and scanning it for viruses first. The Gradle build could only continue once the unzipping and scan was complete, thus leading to very long build times (5 min plus). Since Android Studio, by default, runs a Gradle build when you start up, it manifests as an extremely slow start-up.

这个问题非常容易检查:

当您遇到Android Studio运行缓慢的症状时，请按Ctrl- Alt-Delete并打开Windows任务管理器。 单击Processes选项卡查看活动进程并按CPU排序。如果你看到杀毒软件间歇地占用大量CPU，而Android Studio似乎正在加载，这很可能是同样的问题。 您可以通过查看反病毒软件的扫描日志来进一步验证，检查.jar文件。

要解决这个问题，您必须将正确的目录添加到防病毒软件的“排除文件夹”中。假设你的Windows用户名是“username”，并且你已经在C: drive上安装了Android Studio。然后，您将请求从病毒检查中排除以下目录:

C:\Users\Username\.android
C:\Users\Username\.AndroidStudio2.2
C:\Users\Username\.gradle
C:\Users\Username\.m2
C:\Users\Username\AppData\Local\Android\Sdk

请注意，如果你排除这些目录，你可能需要采取额外的安全预防措施，你应该在工作场所与你的安全部门合作。这可能涉及到在必要时设置自己的Maven存储库。

(我知道这是一个晚的答案，但之前的答案都没有解决这个潜在的问题)

建议:

必须说:如果你有任何机会，花一些钱买更好的PC(cpu)， 这是最重要的…

调整:

Some people say, that OS (Operating System) might cause much slowness. For example, XP or LINUX (or etc) was mentioned to perform 70% faster (don't know why..). Disable VCS by File > Settings > Plugins and disable the following things : CVS Integration; Git Integration; GitHub; Google Cloud ... things; Subversion Integration; hg4idea; Editor is a resource eating too (especially on Large Monitors) and slow. Make it much much faster: click Help > Edit custom VM options and add these lines : -Dsun.java2d.d3d=false -Dsun.java2d.opengl=true save it and Restart Android Studio. If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build and waiting for a timeout. Removing it helps much. File > Settings > Appearance & Behavior > System settings > HTTP Proxy. Another Useful quote (from article): Modules are expensive… On my current project I had to build some libraries from scratch and had to fork some that almost fitted my needs but not quite! If that modules are not constantly modified, it’s important to have this into consideration: the time needed to compile them from scratch, or even to check if the previous individual module build is up-to-date, can be up to almost 4x greater than to simply load that dependency as a binary .jar/.aar. Hint: run the gradle build -profile for an HTML report showing where the time goes regarding the build process. Note: keep that “unnecessary” modules in your version control system for the eventuallity of a quickfix/improvement in that dependency. In your Gradle build script, use only specific Google Service, like: compile 'com.google.android.gms:play-services-maps:...' Instead of full Google Library: compile 'com.google.android.gms:play-services:...' (Compile time goes from 2 minutes to around 25 seconds). Gradle configures every project before executing tasks, regardless of whether the project is actually needed for the particular build. In global gradle.properties adding this will help much: org.gradle.configureondemand=true Surprisingly, some people say , they solved problem by reducing: 1) heapsizes to -Xmx256m (instead of higher values); 2) Emulator Ram-size (from Edit AVD > Advanced Settings);

每天的建议:

不要同时运行多个项目。 使用一次后不要关闭模拟器(每次都使用相同的模拟器运行应用程序;如果你测试大型应用，最好使用真正的手机而不是模拟器)。 每次在模拟器中运行你的应用程序后都清理你的项目-点击构建>清洁项目(或重建)，你可以使用键盘快捷键。
